Here, we report on a fabrication of a graphene on 3D printed alloy substrates with different morphologies using direct CVD synthesis. The number of layers, homogeneity and crystallinity of graphene grown on a large area of a 3D printed metal alloy disks was confirmed by Raman spectroscopy. The microstructure and the morphology of a metal alloy substrate was investigated by atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray photoelectron microscope (XPS), etc. Our results demonstrate a viable and robust process of a direct growth of graphene on non-traditional substates, such as 3D printed and/or arbitrarily shaped surfaces, which could potentially be applied to a synthesis of other 2D materials needed for biomedical industry.
